Power consumption
The power consumed by the kettle during operation is actually the power of the heating element installed in the device.
Two working moments depend on this parameter: heating intensity and electricity consumption. On the one hand, the
high power of the heater allows you to quickly heat up a certain volume of water and saves time. On the other hand, the power consumption of such a device will also be appropriate. The wattage of a kettle's heater typically does not have a significant impact on electricity bills since the energy consumption required to heat a given volume of water remains the same regardless of the heater's power rating. However, there may be certain issues related to electrical connectivity. For example, if the wiring is weak or the fuses are improperly sized, the operation of a high-power heater may cause power outages. Additionally, devices with a power rating greater than 3500 W cannot be connected to a regular electrical outlet and require a specific power format. Consequently, even the largest thermal pots, which typically have a capacity of 10 L or more, are rarely equipped with heaters more powerful than 3000 W, since this power rating is sufficient for their intended use and can be connected to a standard electrical outlet.
Water level indicator
A device that allows you to estimate the amount of water in the kettle without opening its lid. Most often
the water level indicator has the form of a scale applied either to the transparent wall of the container, or to a transparent insert in an opaque wall. In any case, this function allows you to measure the volume of filled water quite accurately, and not just determine it “by eye”. This possibility is especially important for models with open coils (see "Heating element"), in such devices, a mark on the indicator is usually applied to the minimum allowable water level.
Thermostat
A device that allows you to set the temperature to which the water will be heated — the
thermostat monitors the temperature and automatically turns off the heating when the desired value is reached. In fact, water heated in a kettle does not always need to be boiled: for example, for brewing some types of tea, the optimum temperature is about 80 °C, and for preparing baby food — 60 °C. Thermopot are most often equipped with a thermostat, but there are also classic electric kettles with such a function.
Temperature adjustment
The temperature adjustment capabilities refer to the specific temperature values that can be programmed into the electric kettle. It's important to note that this refers to automatic adjustment, where the kettle turns off or switches to temperature maintenance mode once the desired temperature has been reached.
If this paragraph contains several options separated by commas (for example, “60 °С, 80 °С, 90 °С”), this means that this model has several fixed temperature options. However, there are also devices with
smooth adjustment, which allows you to adjust the temperature in steps of 5 °C, or even 1 °C; for such devices, the entire adjustment range is indicated here, for example, "60 — 100 °C".
The greater the number of temperature setting options available in an electric kettle, the more versatile it becomes, allowing for precise selection of the optimal brewing mode for various types of drinks. Here is a simple table of recommended temperatures:
—
white tea — 60 °C;
—
yellow tea -70 °C;
—
green tea — 80 °C;
—
black tea — 90 °C;
— rooibos, hibiscus — 100 °C (up to boiling);
—
baby food — 40 °C.
Of course, there are exceptions to such rules — depending on the specific type of drink.
...For example, some varieties of green tea can be brewed at 90 °C.Control via smartphone
The ability to remotely
control the kettle from a smartphone, tablet or other similar gadget with a special application installed. The connection can be made via Wi-Fi or Bluetooth.
This feature does not only allow you to control the device from a distance, but often gives you more options than the classic control method. For example, special "chips" like a timer or thermostat can only be accessed through the application. In addition, the information about the operation of the kettle is transmitted to the application — for example, thermometer data, status (on/off), etc. Due to plenty of features, models controlled from a smartphone are often called
“smart kettles”. Their main disadvantage is their high cost.
